General issue when copying and pasting shortcodes
Be careful, if copying and pasting shortcodes from blogs, other post on your sites and elsewhere, not to accidentally include <pre> tags as this will means formatting is ignored.
This is a common cause of very strange styles as CSS is ignored.
Generally it is best to manually input the shortcode rather than copying and pasting to avoid this and other issues.
Buttons and other things don’t look good

The downside is that unlike other plugins that have preset styles and customisation controls, that occasionally some CSS tweaks are required to make things look good.
